Title: Overcurrent protection circuit for TV receiver - has overcurrent signal that trips cut-out on isolating transformers generating short circuit primary side
Inventor: DIETHELM OTTO ING GRAD
IPC: H04N3/20
Filed: 1974-12-17
Abstract: The overcurrent protection circuit is intended for a television receiver, and generates a signal on current overload that causes a short circuit on the secondary side of the isolating transformer. The resulting short circuit current triggers a cut-out process on the transformer primary side. The overcurrent signal preferably forces a flyback switch in the ine output stage to switch through. The overcurrent signal may be taken from the junction point between the secondary of a line transformer connected to a high voltage cascade and an earthed resistor, generating a switching signal via a threshold switch. An opposite polarity voltage may be added to that of the overcurrent signal, and the summated signal voltage may be supplied to the threshold switch.
